The paper recyclable heat sealable bag includes a heat sealable water soluble inner layer coating and an article of paper. The heat sealable coating is applied to the article of paper by a printing press. As the printing press applies the heat sealable coating to the article of paper, the paper recyclable heat sealable bag may be wound into a master roll with a plurality of paper recyclable heat sealable bags. The master roll is fed into an automatic packaging system which fills the bags with a product from at least one of a top edge and a side edge of the paper recyclable heat sealable bags. The paper recyclable heat sealable bag has certain perforations to remove the paper recyclable heat sealable bag more easily from the master roll and sealed with a heat sealer.

A method includes separating a portion of a flattened tube of stock packing material to a custom length to form a pouch pre-form and closing a first end of the pouch pre-form leaving a second end of the pouch pre-form open. The method can include placing product into the pouch pre-form and closing the one open end of the pouch pre-form to form a closed pouch containing the product.

Apparatus and method for filling bulk materials into open-mouth bags, including the following steps: a) an open-mouth bag is appended from beneath to a filling spout of a filling station by way of an at least partially upwardly motion, so that the bottom end of the open-mouth bag is freely suspended; b) the filling process is started and bulk material is introduced into the open-mouth bag so that the freely suspended bottom end of the open-mouth bag unfolds; and c) the filling spout is lowered, so that the unfolded bottom end of the open-mouth bag is supported.

Packages made from flexible material, wherein the packages include one or more self-folds formed by applying activation energy to the flexible material are presented. The packages include a polymeric film, wherein the polymeric film is formed from one type of polymer, and wherein the flexible material defines an enclosed product volume. The packages include a first panel formed from the flexible material and a second panel formed from the flexible material. The packages include a self-fold that has an overall thickness that is about 5% to about 30% greater than a thickness of the flexible material outside of the self-fold. The self-fold has a differential thermal-mechanical set than the flexible material outside of the self-fold, and forms an angle of about 100 degrees to about 170 degrees between the first panel and the second panel.

A feeding device for an electrostatic bag, adapted for supplying electrostatic bags to a package mechanism so as to warp an SSD with an electrostatic bag, includes two carrying mechanisms arranged up and down, which respectively support at least one reel that is wound with multiple electrostatic bags. A feeding position is provided between the two carrying mechanisms and face the package mechanism. The two carrying mechanisms are movable up and down to switch positions with one another. The feeding device for an electrostatic bag can supply electrostatic bags to a package mechanism, reload the electrostatic bag without stopping the machine, and ensure the continuous operation of the package mechanism.
